After serving as a consultant to New York City Mayor Michael Bloomberg’s re-election campaign, Howard Wolfson has now joined the Bloomberg administration in a full time role as senior adviser, The New York Timesreports.

Wolfson “will assume the newly created position of counselor to the mayor, focusing on communications and policy,” says the Times.

After serving as communications director on Hillary Clinton’s 2008 presidential campaign, Wolfson joined Fox News as a contributor, became a blogger for The New Republic and took a post as managing director at consulting firm Glover Park Group.

Some called Wolfson a “high profile attack dog” while he worked on Bloomberg’s re-election, a race that was much closer than expected given the campaign’s massive monetary advantages over challenger Bill Thompson.
